To aZZ whom it a concern;

- Be it known that I, ALBERT L. HALE, of Chicago, county of Cook, andState of Illinois, have invented a new and useful Improvement in Meansfor Operating Tools upon Irregular Surfaces, of which the following is aspecification.

My invention relates to machines for transmitting power for operatingrotary bru'slies or abrading-tools for cleaning or polishing surfaces,driving drills, or other similar cutting-tools, but more especially foroperating brushes or shears in grooming horses or other animals, myobject being to provide a construction adapted to operate tools uponvery irregular surfaces and in any direction, the same being describedhereinafter and illustrated in the accompanying drawings, in which--Figure 1 is a side elevation showing the niachine as it appears whenadapted to operate a rotary brush. Fig 2 is an elevation at a rightangle to what is shown Fig; 1 or in the direction indicated by arrow 8of a shorter machine than is shown in Fig. l and with the brush or toolshaft broken away. Fig. 2 is a plan below broken line 13 13 of Fig. 2.The broken lines 9, 10, 11, and 12 of Figs. 1 and 2 show angles out towhich and beyond the ma-. chine may be swung laterally when necessary inreaching surfaces at different distances from the normal center line ofthe suspensionrod. Fig. 3 shows, respectively, a side and a frontelevation of a hanger adapted to suspend the operative partsfrom theceiling. Fig. 4 shows, respectively, a side and front elevation and aplan of a shaft and pulley frame which is pivotally mounted in thehanger shown in Fig. 3. Fig. 5 shows, respectively, a front and a sideelevation of a yoke and a top portion of a suspension-rod attachedthereto adapted to connect the parts hereinbefore described with anadjustable spring swivel device, which latter is shown in Fig 6 on alarger scale than in the preceding figures. Fig. 6 shows the lower endportionof the suspension-rod, together with the lowest end portion ofthe rod, which is screwthreaded for a short distance and hasscrewthreaded nuts mounted thereon, and there are guide-pulleys mountedona pivotally-attached. frame and a horizontally -disposcd tool-drivingshaft having one end mounted to revolve in said attached frame, allshown in elevation, while ahelical spring and a portion of aswivel-frame and the tool-shaft-driv ing pulley, together with thecasing for this shaft, are shown in axial section, indicated by thedirection of broken line 14, Fig; 2, with the exception of the lower endof the swivelyoke, Fig. 6, which is iii elevation. The

broken lines 15 and 16 of Fig. 6 indicate po sitions to which thetool-shaft maybe swung to vertically, and a much greater angle may bereached, if necessary; in practicewithout materially interfering withthe tension of the- Vertically disposed driving belt. Fig. 7

shows a flexible tool-shaft in elevation, with one end of an elasticcovering therefor shown as it appears when slitted longitudinally andopened to expose a helical-spring shaft within, which is adapted toconnect the horizontallydisposed tool shaft with the brush or othertool, as shown in Fig. 1. j g

The ceiling hanger has two downwardly projecting portions A and A,between whose lower ends the rectangular frame B is pivotally mounted tovibrate or swing on oppositely-disposed bolts B andB 'At a right angleto these pivotalbolts are bosses on frame B, in which are secured theends of a stationary cross-shaft C, Fig. 4., extending diamet ricallyacross frame B, and loosely mounted to revolve on the shaft is a pulleyD, having a double groove to receive a driving and a driven belt fortransmitting power, as'hereinafter described. At each end of the shaft0,

close to frame lithe-upper ends of the arms of a yokeE are mounted toeasily swing thereon and to straddle the pulley D. At the lower end ofyoke E is securedthe upper end of a suspension-rod F, whose lower endter minates in a tail-rod having a portion next the suspension-rod at Fscrew-threaded and with screw-threaded nuts. mounted thereon.

The greater part of the lower portion of the tail rod is cylindrical andis fitted to easily slide longitudinally and vertically in a hole in thetop of a swivel-buckle G, the buckle also being adapted to revolvearound the rod for the purpose hereinafter explained. A helical springis mounted on the tail-rod and has bearing at the top against the nuts Fand at the bottom end against the top of swivelbuckle G, whereby theswivelbuckle is forced downwardly, but limited in its downward movementby the stop-pin F Fig. 6, contacting the under side of the head of thebuckle. The lower end of the buckle G is pivotally attached to apulley-frame H by means of a transverse bolt II, whose pivotal center ison the same line transversely as the pivotal centers of two pairs ofbelt-guide pulleys I J and K L, which are mounted at the sides near thetop of frame H.

In the lower portion of frame Hand at right angles to the pivotal centerH of buckle G is mounted the end of a horizontally-disposed revolubleshaft M, a grooved pulley N being secured thereto between the lower armsof the frame H. Pulley N is connected with pulley D at theceiling-hanger by means of a round belt 0, which passes up and downbetween the opposing pairs of guide-pulleys I and J and K and L. Shaft Min this.instance is disposed within a tubular holder P, which has oneend firmly secured to the pulley-frame II, so that its outer end mayform a bearing for the outer end of shaft M, as shown at M Fig. 6. ShaftM terminates in a screw M, in this instance, whereby a helical wireflexible shaft may be attached thereto by being screwed thereon, in theusual manner of attaching such shafts.

In Fig. 1 is shown a form of flexible shaft which is particularlyadapted to use in transmitting power for machines of this class, and itsnovelty consists in covering the coils comprising the ordinary helicalshaft with an elastic covering of india-rubber R in the form of ajacket, which in practice serves to yieldin gly hold the coils of theshaft in proper position, whereby the shaft may be made to transmit muchmore power without undue vibration when bent at a sharp angle than canbe attained .by the same shaft with an ordinary inelastic covering.

Although the flexible shaft B may be coupled to shaft M by being screwedonto the screw-threaded tenon M, as stated, there are other methods ofcoupling in common use which may be adopted for machines of this kindwhich revolve either Way and which may be quickly uncoupled or coupledwhen intended for driving several different kinds of tools which areoften changed.

At R is a handle which is loosely mounted on a spindle R which forms theouter termination of flexible shaft R, which latter is usually directlycoupled with any tool which is being operated, as shown in Fig. 1.I'Ielical spring F is f or the purpose of forcing the pulley-frame H andpulley N downwardly to yieldingl y ad j ust or control the tension ofbelt 0 as it may lengthen by extended use or when under the strain ofduty. The use of this tension device also prevents to a great degree anunskilled person fastening the belt with too great or too small atension to properly operate the tool.

By the use of this device it is not necessary to shorten the belt untilby the increased length thereof the swivel-buckle G contacts with thestop-pin F (See Fig. 0.) The belt may be shortened until theadjusting-nuts F are screwed up to the upward limit of the threadedportion F of the tailpiece of the suspension-rod, the nuts being screweddownwardly from time to time as the belt becomes loose.

Ordinarily, in practice, a rotary motion is imparted to pulleyD by meansof a round belt in communication with some source of power, and motionis transmitted vertically downwardly to pulley N, shaft M, and theflexible tool-shaft R by means of round belt 0, which is guided or heldin line With'the plane of rotation of pulley N by the pairs of pulleys IJ and K L at opposite sides, as before stated.

The pivotal centers of suspension at the ceiling-hanger being placedrelatively at right angles to each other, the suspension-rod F may beswung from the position shown laterally and upwardly in any direction,and since frame H is attached to swivel-buckle G by means of ahorizontally-disposed pivotal ce nter 11 and the swivel-buckle is somounted on tail-rod F that it may revolve entirely around in ahorizontal plane it is obvious that shaft M may be swung around andupwardly in any direction necessary in connection with flexible shaft Rto adapt the machine to operate tools upon surfaces subtending any angleto a vertical or horizontal plane, which particularly adapts it touse'for grooming animals or for cleansing castings or objects of veryirregular form.

I claim as my invention-- 1. The combination, with a hanger, theprojecting portions of which extend laterally and are perforated in aline with each other, of a frame journaled therein, the sides of whichare raised and perforated in a line with each other, a wheel and a yokejournaled in said frame, the yoke being provided with a' suspension-rod,a flexible shaft supported by the rod, the outer end of which is adaptedto receive a tool, and a belt over the pulley in the frame and over theinner end of the shaft.

2. The combination,with a hanger-pulley,

of a suspension-rod, a flexible shaft yieldingly supported by said rod,means for regulating and limiting the tension of the support, and a beltover the pulley and over the inner end of the shaft, the outer end ofthe shaft being adapted to receive a tool.

3.
